    • Performance Analysis of DCT and DWT Algorithms in Image Steganography 

      Najeeb, Al Anood; Maadeed, Somaya Al; Maadeed, Noor Al ( Qatar University Press , 2021 , Poster)
      Frequency domain techniques such as Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) ensures high accuracy when compared with the spatial domain techniques. Therefore, these image steganographic methods ...
